Tekle Giyorgis I (Amharic: ተክለ ጊዮርጊስ "Plant of Saint George") was Emperor of Ethiopia (throne name Feqr Sagad) intermittently between 20 July 1779 and June 1800, and a member of the Solomonic dynasty. He was the youngest son of Yohannes II and Woizoro Sancheviyer, and the brother of Tekle Haymanot II.

According to Sven Rubenson, who described Tekle Giyorgis as the last emperor to exercise authority on his own, "It is not without justification that he has in Ethiopian tradition received the nickname Fiṣame Mengist, 'the end of the government'".
